Story summary

On October 31, 2026, the U.S. Embassy in Moscow issued a rare and urgent warning about a credible threat of a "mass casualty event" at the Tsaritsyno Museum Reserve in Moscow, advising visitors to avoid the area and stay alert. The museum, an imperial palace and park complex popular among tourists with over two million visitors annually, was temporarily closed by Russian authorities as a precautionary measure. In response to the warning from the U.S., Russia's Federal Security Service (FSB) confirmed receiving information about potential terrorist preparations in Moscow through established partner channels and stated it was taking appropriate security measures. Meanwhile, Global Affairs Canada echoed the U.S. alert, advising against all travel to Russia due to risks of terrorism and ongoing conflict with Ukraine.
